There's some talk of regulation, and people who never knew individuals getting in on the act.
For those who so choose, I'd prefer to see options: 1. Person can set who gets to see their content after they pass, before they pass away. A part of their will. 2. People having access to the content of the person who has passed have ways to handle that as they wish. (Never see it, only see it when I ask etc.)
For those who choose not to prepare in advance, they might get the default, which they can change.
